The new Mascara 38°C has a stretching effect on the lashes that goes far beyond their natural length. As each lash reaches its dream length, it is immersed in deep, glossy black. At the same time, the lash line is styled so perfectly that it is like an open fan, framing the eyes.Smooth Streching Formula:LASH LENGTHENER 38°C achieves this stretching effect and thus the coveted extension with the Smooth Streching Formula. This ingenious technology does not require any added fibers. The liquid formula consists of two layers. The first is a pliable polymer, which achieves the stretching effect through its elasticity. The second, a micro emulsion polymer, gives structure and brings the deep black, shiny lashes into top shape.Lash Catching Brush: This brush reaches every lash. Each brush hair is triangular in design, with three grooves on each side. This serves to store the optimal amount of mascara between the grooves, carefully coating each lash. The finely woven brush hairs reach every lash from the inner to outer corner of the eye. Even the shortest, which is barely visible to the naked eye, is consistently given the longest possible length. From the base to the tip.Application: To achieve the highest possible lengthening and optimal curl, slowly pull the brush up from the base of the lashes to the tips. Please DO NOT apply in a zig-zag, as this will prevent clumping. Like all mascaras in the SENSAI 38°C Collection, the new LASH LENGTHENER features thermosensitive technology. It is reliable, smudge-proof and waterproof. The mascara can be removed very easily with water, from a temperature of 38°C and the SENSAI SPONGE CHIEF or a cotton pad.
